This invention relates to improvements in waste systems and is directedmore particularly to a novel waste system for trapped units in a house,office building, or the like.

It is one of the principal objects of the invention to provide a wastesystem whereby the usual trapped units of a building such as thetoilets, water basins, etc., may be more readily and more eflicientlydrained. The system of the in-- vention includes a novel valvearrangement which, in association with the other parts of the system, isadapted to overcome the objections of the present-day systems not onlymore eiliciently than has been heretofore known but at less cost.

It is also an object of the invention to provide a distinctive valvedevice for associating in a Waste system whereby air is readily admittedthereto at desired places and times.

Various other objects of the invention will become more apparent after areading of the following description and particular reference will behad to the accompanying drawing, wherein:

Fig. 1 is a side elevational view of a waste system embodying thefeatures of the invention; and

Fig. 2 is a side elevational view with parts in section of one of thevalve devices of the invention.

Referring now to the drawing more in detail, the invention will be fullydescribed.

In Fig. 1 there is a substantially vertical pipe 2 which I call a wasteriser. This extends up through the floors of the building so as toreceive drainage from the various trapped units thereon and it has atrap 4 in its lower end. There is also an outlet 6 and preferably acleanout plug 8 is associated with either the trap 4 or the pipe 2 asdesired.

As is well known, buildings of ordinary construction include a number oftrapped units, such as at least one toilet and one wash basin on eachfloor. One of the objections to present day systems is that when atoilet, for example, on a higher floor is flushed the rush of watertherefrom into the waste riser creates a substantial suction and drawssome at least of the water from out of the trapped units on the lowerfloors.

Such a situation is, of course, undesirable since no water can get backinto the upper trapped units until the same have been manually operatedto draw Water thereinto again. Thus, of course,

1937, Serial No. 129,396

the units would not be sealed against the waste riser which, of course,is objectionable.

With reference to Fig. 1 there is shown a water basin W of ordinary formhaving a trap 20 and a pipe 22 associated therewith leading into thewaste riser 2: A toilet bowl is indicated at B in Fig. 1 and this alsohas a trap 30 and a pipe 32 leading into the riser 2.

It is desired to point out that the trapped units, as well as the traps,may take many and various forms but, as is well known, they are alladapted to hold water therein when desired and drain into the riser whendesired.

There is shown at B a lower toilet and this has a trap and an outletpipe 38. It will be noted that the pipe 32 leads into the riser 2 at apoint below pipe 22 and that pipe 38 leads into the riser at a pointstill farther below.

It will then be appreciated that the flushing of toilet B will cause thedrainage thereof and the water rushing therefrom into the waste pipe 2will setup a suction or syphoning effect therein. This will draw waterfrom out the trapped units W and B and into the waste system, which, aspointed out above, is objectionable. Furthermore, such syphoning actionhas the tendency to break the trap seal and allow obnoxious sewer gasesto escape back into the rooms containing the fixtures.

According to this invention, however, means is provided whereby thisobjectionable effect is overcome. That is, I provide for air to beadmitted into all of the trapped units whenever the suction effect isset up in the system and thus prevent the trap seals from being brokenor the trapped units from being undesirably drained.

This means takes the form of a valve device II] which I associate withopenings in the outlets leading from the traps to the waste line. Whilethis device may take various forms, it preferably includes a casing 40which is adapted to be associated with the outlets in some suitable wayand this has an opening surrounded by a seat 42.

A reciprocating piston 44 is provided and this has on its inner end avalve disc 46 adapted to seat against seat 42 in the casing. Springmeans such as 43 may be provided to urge the valve disc into the closingposition shown in Fig. 2, while there may be a stop to limit thedownward movement of the rod 44. There may or may not be a covering suchas 50 secured to the outer end of the rod.

With this arrangement as air is drawn downwardly in the riser 2 by thedrainage from one of the trapped units, it will be seen that atmosphericpressure causes the valve disc 46 to be moved away from its seat so thatthe opening in the valve casing is uncovered and in communication withopening 36 in the outlet. Thus air is immediately admitted to the otheroutlet pipes and the suction that would otherwise be set up iscounteracted.

With reference to Fig. 1, it will be noted that the valve device loverlies an opening 36 in outlet 32 and there may be a lip or gland suchas 34 associated therewith to prevent drainage from escapingtherethrough. It will be noted that gland 34 is of such form and solocated that the water is directed downwardly and its flow through theoutlet pipe is facilitated.

The gland 34 thus also serves to prevent drainage from clogging theopening 36 or from becoming lodged near the valve. The lip 34 may, ofcourse, vary in size and shape.

While I have described the invention in great detail and with respect toa preferred form thereof, it is not desired to be limited thereto 1. Thecombination with a waste pipe of a trapped closet bowl having adischarge, a connection between the discharge and waste pipe, a ventvalve in said discharge, and a gland in said discharge overlying thevent valve.

2. The combination with a closet bowl having a trap and avertically-directed discharge and an opening leadinginto said discharge,a valve in said opening adapted to be opened by suction in saiddischarge, and a gland extending downwardly in the discharge spaced fromand disposed over said opening.

3. A closet bowl formed to have a trap and a discharge for connecting toa Waste line leading downwardly therefrom, the wall of the bowl aroundthe discharge having an opening therethrough, a valve device over saidopening having an opening normally closed by a spring-pressed memberadapted to be moved to open position by suction in the discharge, and agland in the said discharge extending from above the opening in the wallof the bowl outwardly and downwardly at a distance from the opening withits lower end spaced from said wall to provide pro-. tection for theopening and admit the passage of air through the valve into thedischarge.
